>> It might seems so because I'm interleaving discussion of two different desires: FastCGI and scalable socket servers. If this isn't needed for FastCGI so much the better, but if one were to make a sort of Node.lc I would imagine they'd need to hand off socket connections to workers, no?
Or you could just act as an intermediary accepting connections from whatever is making the request and then routing the incoming data to the appropriate child process.

We didn’t get that far

We are going around in circles here a bit. Check the docs for mod_fcgid where there are settings to control the number of processes and spawn rate https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html <https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html>
The nuts of it is that mod_fcgid will start a new process if it has permission to and there’s a request but no idle processes.
